MOSCOW -- Round three of the talks in Geneva between Iran and the permanent members of the Security Council, plus Germany, over Iran's nuclear program ended Thursday without a signed agreement. But the dialogue goes on between Iran and the international community.

"A lot of progress was made, but of course differences remain in our plan. Our hope is to narrow some of those differences," said Michael Mann, spokesman for E.U. Foreign Policy chief Catherine Ashton.

Meanwhile, Israeli Prime Minister Benjamin Netanyahu told a gathering of local Jewish leaders in Moscow Israel would not obligate itself to a bad deal, promising them Iran would not get nuclear weapons on his watch.

After a two-day visit in Moscow, Netanyahu still faces an uphill diplomatic battle to convince Russia and the rest of the international community not to sign an agreement with Iran.

"I think it's been a tremendously uphill battle," Jerusalem Post diplomatic reporter Herb Keinon told CBN News. "First of all, you're going up publically against the U.S., your greatest ally, and then you have to push all these other countries who are generally following the U.S. except for Russia and China."

Keinon says Netanyahu's efforts are making a difference.

"Netanyahu standing up on every rooftop and screaming this is a bad agreement I think it does have an impact on those sitting in the room with the Iranians," he said.

While Iranians negotiated in that Geneva room, their Supreme Leader Ayatollah Khamenei made some revealing statements.

Khamenei called Netanyahu "…the sinister mouth of the unclear rabid dog of the region in the Zionist regime." He added, "The Zionist regime is an imposed regime…and this regime will not endure."

Netanyahu told CBN News in an off-camera briefing that securing the future of the Jewish state is what moves him.

Keinon says Netanyahu feels called for such a time as this in Jewish history.

"He feels the weight of Jewish history. I think he feels responsibility for Jewish history," Keinon said.

"You have a regime right now that is threatening to annihilate the State of Israel, and I think he feels very much a historical role of preventing that, come what may," he continued. "If it means creating some tension with the U.S., then so be it. If it means standing up in the face of world opinion, so be it. If it means taking some bad New York Times editorials, so be it. That's why I'm here, that's my role. That's maybe my fate and that's what I'm going to do."
